Power Loss Ride Through
Time
Sets the maximum time that the drive will wait until trying to restart after power loss.

Undervoltage Detection
Lvl (Uv1)
Sets the voltage at which a
Uv1 [DC Bus Undervoltage]
fault is triggered or at which the
KEB function is activated. Usually it is not necessary to change this setting.
NOTICE:
Damage to Equipment. When you set this parameter
to a value lower than the default, you must install an AC reactor
on the input side of the power supply. If you do not install an AC
reactor, it will cause damage to the drive circuitry.
Determined by o2-04 and

Note:
When
L2-29 = 1, 2, or 3 [Kinetic Energy Backup Method = Single Drive KEB Ride-
Thru 2, System KEB Ride-Thru 1, or System KEB Ride-Thru 2]
and you do KEB Auto-
Tuning, the drive will automatically set this value.
